Records gastric parasites in young salmon, 15 per cent being infected 

 on the average. "It is evident that residence in fresh water is con- 

 ducive to the growth of parasites in the stomachs of young salmon." 

 In spawning salmon, intestinal parasites frequent. Another common 

 pest of the salmon in fresh water is a parasitic copepod which attaches 

 itself to gill filaments. There are not usually very many on one fish, 

 but sometimes the gills are almost destroyed by them." (See plates 13 

 and 15.)

Fish are sometimes infested with parasites, some of them microscopic 

 and of serious effect. But little is known of fish diseases.

 Central Station, Washington, D. C. Bulletin U. S. Fish 

 Commission, vol. x, 1890, p. 1-12, pi. 1-4. 



Goldfish and carp frequently infected by minute infusorian not de- 

 termined: catfish, sunrish, white perch, trout and others infested in 

 winter by Chromatophagus parasiticus (Ichthyophthirius). All have 

 yielded to brackish water treatment. Parasite most persistent and 

 troublesome in fresh-water aquaria. Few fresh-water fish free from 

 its ravages.

Parasitic diseases offer a wide field for investigation. Remove dis- 

 eased individuals. An aquarium once infected is difficult to clear of 

 parasites.
